Radar Imaging of Near Earth Asteroids
May 9 & 10
Radar is a very powerful astronomical technique for studying the
physical properties and refining the orbits of near-Earth asteroids.
The world's only two radar telescopes for imaging asteroids are at
Arecibo, Puerto Rico, and Goldstone, California. These telescopes
can image near-Earth asteroids with resolutions as fine as several
meters, which greatly exceeds the finest resolution available from
any ground- or space-based optical telescope (even the Hubble Space
Telescope). Radar images reveal an object's size, shape, rotation
state, and features on its surface such as craters, ridges, and even
large boulders, and have discovered that 1/6 of near-Earth asteroids
larger than 200 meters in diameter are double systems that revolve
around each other, like miniature versions of the Earth and Moon, and
that 10% of near-Earth asteroids look like gigantic peanuts, while
others resemble muffins and potatoes!
